Figure 3

Electron micrographs of L1 capsomere derivatives. Purified proteins were placed on carbon-copper grids, treated with uranyl acetate, and visualized using transmission electron microscopy. The samples are: full-length L1 capsomeres generated from dithiothreitol treatment of purified L1 VLPs (Panel 1); C-1 (2); 3-1 (3); and 423-3 (4). The bar in Panel 1 represents the scale of the microscopy images.
